The expression of migration inhibitory factor in peripheral blood mononuclear cell and its correlation with disease activity in systemic lupus erythematosus
Objective To investigate the change of macrophage migration inhibitory factor (MIF) mRNA
expression in peripheral blood mononuclear cell (PBMC) and serum MIF and its correlation
with disease active index in patients with systemic lupus erythematosus (SLE). Methods MIF
mRNA expression of PBMC and serum MIF in patients with active and inactive SLE was
measured by reverse transcriptase-polymerase chain reaction and enzyme-linked
immunosorbent assay, respectively. The correlations of serum MIF with SLE disease active …

Objective
To investigate the change of macrophage migration inhibitory factor (MIF) mRNA expression in peripheral blood mononuclear cell (PBMC) and serum MIF and its correlation with disease active index in patients with systemic lupus erythematosus (SLE).
Methods
MIF mRNA expression of PBMC and serum MIF in patients with active and inactive SLE was measured by reverse transcriptase-polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. The correlations of serum MIF with SLE disease active index, serum ds-DNA antibody, ANA, C3, C4 and IgG were examined.
Results
There was marked increase in MIF mRNA expression of PBMC and serum MIF in patients with SLE than that in normal volunteers (P< 0.01). Level of MIF in patients with active SLE was higher than that with inactive SLE (P< 0.01). There were significant correlation between the blood MIF concentration, MIF mRNA expression and SLE disease active index, ds-DNA antibody, C3, C4 and IgG, but no significant different was observed between the blood MIF and antinuclear antibody.
Conclusions
MIF mRNA expression in PBMC and serum MIF concentration is significantly increased in patients with SLE and correlates with SLE disease activity. Serum MIF levels may be a useful parameter for monitoring disease active in patients with SLE.
